Fixed formatting and a bit of grammar.

| May 22, 2017 at 22:23 | comment | added | Sotiris Dimitras | Mr David, At the very beginning I was trying to generate a grammar using the hint that was provided as an answer. However I thought of a different way to solve my problem and i was trying to figure out how to decrease the number of "a" into half. I have to apologize because I was not clear what I actually wanted to ask. Moreover, I figure out a way that could be solved and I posted as an answer at the question, as well as the unrestricted grammar. Thank you for your time. | |
